Hi,
I found a little bug in the test/makefile of the luabind-0.7 release
(January 24, 2006).
I downloaded the luabind-0.7 tarball on the sourceforge page.
It compiled except the test directory. The error is:
-------
/usr/lib/liblualib.so: undefined reference to `dlerror'
/usr/lib/liblualib.so: undefined reference to `dlclose'
/usr/lib/liblualib.so: undefined reference to `dlopen'
/usr/lib/liblualib.so: undefined reference to `dlsym'
-------
Indeed, it is because '-ldl' is missing in the makefile. I simply
suggest to add it at the end of the concerned line:
-------
$(CXX) $? -o $@ -g -L$(LUA_PATH)/lib -L../lib -lluabind -llualib
-llua -ldl
-------
Could you please update the tarball, so that source-based Linux
distributions (like Gentoo) could download and compile it without
problems ?
Thanks in advance.
Best regards,
Cyril
